EXCAVATING-BUCKET.

SPECIFICATION forming part of Letters Patent No. 747,480, dated December22, 1903.

' Application filed June 17, 1903. Serial No. 161,893. (No model.)

To all whom it may concern: of mechanisms which are in turn controlledBe it known that I, HENRY L. REYNOLDS, a by the swinging of the hangers.citizen of the United States, and a resident of In the drawings, 1represents the scoops, Jersey City, Hudson county,New Jersey, have twoof which are provided, said scoops pref- 5 invented certain new anduseful Improveerably having a bottom and two sides, the

Four of these hangers are in the followingspecification and its scope employed, two for each scoop, the same beingwill be defined by the claims terminating the placed one at each side ofa scoop.

In order to se- If the pin 32 is maintained onthe central cure this action, the scoops (by which term line of thebucket while the two parts are 45 I mean the lower bucket-like memberswhich separated by the swinging of the hangers, and 5 contain thematerial) are pivotally carried-by if at the same time this pin bemoved-downhangers or levers, which in turn are pivoted wardly upon suchcenter line as-the hangers at or near their upper ends so as to swingswing outwardly, the scoops will during the toward and from eachother.The scoops are major part of their outward movement be 50 controlled intheir angular position by means maintained approximately in the sameanguloo 'lines in Fig. 1.

larposition as when closed, and during the latter part of the outwardswinging movement of the hangers the buckets will be rapidly rocked intothe vertical position shown by the broken In order to secure thisaction, I have connected the pivot 32 by means of links 4, which, ineffect, form a toggle with the outer ends of extensions 2 of the hangersbeyond their pivot 3. These extensions lie upon the opposite sides ofthe pivot 32, from the hangers of which they form a partthat is, theextension 2, which lies at the right of the center line of the bucket,isa part of the hanger 2, which lies at the left of the center line ofthe bucket, and vice versa. I have herein shown these extensions asbeing substantially horizontalin the closed position of the bucket. Theexact angle made by these extensions, as well as by other parts of thedevice, and also the relative lengths of the parts and locations of thepivots, may be widely varied without changing the essential character ofthe invention. By varying these parts the action ofthe device may bewidely changed.

As the hangers are swung outwardly the extensions 2 swing downwardly,which carries the toggle-links 4 downwardly and at the same time closesthe toggle, which tends to carry the central pivot thereof, 32,downwardly at an increased rate. The position of the parts when thebucket is opened is shown by the broken lines, composed of alternatedots and dashes, in Fig. l. The first action of the toggle-links 4 uponthe scoops 1 is to depress the outer ends thereof; but this depressionis counteracted somewhat by the fact that the links 15 are primarily ataconsiderable angle relative to the direction of the hangers 2. As thehangers near the outer portion of their swing the links 15 pass thehorizontal position and farther movement downward draws inward the outerend of the bucket. At the same time the inner ends of the bucket-scontinue moving outwardly, which results in a rapid rocking action uponthe bucket, which quickly turns it into the vertical position.

The means provided for opening or swinging outwardthe two parts of thebuckets consists of toggle-links S, which are pivoted to the hangers at30 and have a common or center pivot 31. The pivots 30 are removedlaterally from the center line of the bucket, so that if the commonpivot 31 be moved upwardly the hangers will be swung outward orseparated. This central pivot 31 is moved upwardly by means of anopening-rope,which is connected thereto. This opening rope might beconnected directly with the pivot 31, but in some cases such aconnection would not provide a sufficient opening power. In such eventthis power may be increased by the means which are clearly shown in Fig.2. As therein shown, a single opening-rope 16 islocated centrally of thebucket and at its end is branched so as to provide two end sections 6.The lower or central pivot for the toggles is in the form of atransverse shaft 31, which connects the two toggles at opposite sides ofthe bucket. Upon this shaft are mounted two pulleys 9, which liesubstantially in the central transverse plane of the bucket. The twobranches 6 of the opening rope each pass about one of the pulleys 9 andthen upward. Each of these branches may then be directly connected withthe transverse shaft 3, which forms the pivot for the hangers, or, as isherein shown, they may be passed around pulleys 19, carried by saidshaft, and thence downwardly and be attached to the shaft 31. Itisobvious that by pulling upon the openingrope 16 the shaft 31 will bepowerfully drawn upward or toward the shaft 3, which will open out thetoggle-links 8, and thus separate the two parts of the bucket.

The closing means shown consist of pulleys 7, mounted upon the hangersas near to their lower ends as convenient, about which extend theclosing-ropes 70, one rope being used at each side of the bucket. Thepower of these closing-ropes may be increased by increasing the numberof pulleys 7. I have herein shown two such pulleys upon each hanger. Oneend of the closing-rope is socured to one of the hangers by any suitablemeans and thence passes about the pulleys 7 and thence upward through aguide or over a pulley 17, located adjacent to the pivot of the hangers.

I prefer that the rods 30, by which the opening links or toggles 8 arepivoted to the hangers, be located at such a distance from the pivot 3of said hangers that the extensions 2 of said hangers may swing withinsaid rods 30. In some cases there may be no necessity for suchclearance. The toggle-links 4, which together with the extensions 2 andlinks 15 constitute what I have called the scoop-controlling orposition-controlling devices, are preferably placed outside of the planeof the opening links or toggles 8, so that their centers may freelypass.

I do not wish to be understood as limiting myself to the exactconstruction or operation of parts herein shown and described, but toclaim any construction which falls within the scope of the claimsterminating this specification.
